    Oh No, whats that noise...

    Working on my out drive on the stand, prepping every thing for U-joint surgery. Pop it out of gear and turn the input shaft over by hand and I'm greeted by a horrible screeching noise :eek: Visions of my work and cost going up by a factor of 10 run thru my head as I drain the oil (clean with...

    allignment for U-Joint replacement

    I'm about to replace the u-joints on my 1979 one drive, 1.65 ratio (165 L6 motor). Tool for removing the retainer nut is on the way as are the new u-joints (Spicer 5-1306X). In reading thru the manual I'm seeing that if drive gear for the 1.65 only, and only if its the G-7 date code on the...

    Broken lifter and worn cam lobe

    I've been chasing a high RPM backfire into the carb issue for about 3 months now and finally believe I have a smoking gun. The attached photo shows the lifter from the #4 exhaust. The cam lobe is worn almost completely round, it was just cracking the valve open. Any thoughts on what might...

    Mercruiser 160 block for 165 rebuild?

    Is the block from a 1969 160 the same as a 1979 165? The heads use a different style intake/exhaust manifold and the timing marks are on opposite sides of the block, are there other differences I should be concerned with? The 160 block has a fairly fresh set of 30 over pistons, the head has an...

Boot has completely separated at the first section and has 1/2 around broken on the 2nd. I used parts ordered in by my local shop, a reputable shop in the business for the last...

    165 l6 voltage regulator and ignition woes?

    I'm having fits with a 1979 Mercruiser 165 i6 with a skip/backfire thru the carb issue. Backfires under load and has low power, idle is a bit on the rough side. It will hold 600 rpm but its a bit rough and uneven, sometimes better than others. Boat ran fine for the first 30 minutes of first...

    165 I6 miss

    I've got a 79 165 inline 6 cylinder that has developed a popping sound at throttle. Sounds like it is backfiring thru the carb... A bit of history: I bought the motor and out drive in a 79 Marquis with bad transom as a donor for my 69 Sea Ray 185. Motor and out drive both ran great in the...

    6.9-9" tires

    I've got a 1969 trailer that has 6.9-9" tires in need of replacement. None of the local stores I've called have a clue, I've found a couple of on-line sources but am afraid that none of these guys have a clue about mounting. The rims bolt together, I've removed the bolts from one of the rims...

    165 I6 backfiring thru carb under load

    Just got back from the lake for the first time with my 69 Sea Ray with 79 165 inline 6 transplant. All went well for the first hour, some stalling issues going from idle. The transision from idle to butterfly opening is rough and had to work a bit (feather the trottle, open and closing rapidly...

    Mercruiser 165 I6 transplant

    First thanks to all who have responded and gotten me this far, I've already learned much (some even before I made costly mistakes). More questions... I'm in the process of resurrecting a 69 Searay 185 with a Mercruiser 160 inline 6 and early 1 drive. I've found a 79 Marquis with a good...

    Bell housing removal on 1969 1 drive?

    How do you remove the pins holding the bell housing on a 1969 one drive (mated to a 160 I6)? All the documentation I've come across shows the pins covered by the trim position senders and come out with the 12 point tool. I've gone thru service manual #1 (which appears to be my drive and motor...

    Top dead center?

    How do you get the #1 piston at TDC on a Mercruiser 160/1 drive (1969 vintage)? I'm trying to re-install the distributer on the above and can't seem to get lucky using the starter to end up on TDC. On an auto there's room to get a breaker bar on the crank and turn things over but I'm not...

    Bad exaust riser and water in oil
